SSK NVMe SSD Cloner, M.2 Duplicator Dual Bay NVMe Enclosure, Tool-Free 20Gbps USB3.2 Gen 2X2 SSD to USB Adapter M.2 Docking Station for M Key PCIE NVMeSSD Reader Supports Offline Clone

Despite some negative reviews, this particular unit performed flawlessly for me. I initialized the new 2TB M.2 PCIe NVMEquali drive by inserting it into the source socket, USB connecting to a Win 10 laptop, using the Win 10 disk manager (which recognized the new, non-initialized, non-formatted, non-partitioned drive) to create a simple volume and format it. That allowed Explorer (as well as disk manager) to recognize it with correct 2TB capacity. Installed 1TB source and 2TB target in deck, AFTER DISCONNECTING DECK-LAPTOP CABLE. Powered up and got source/target leds lit. Hit "clone" button for 5 seconds to get all leds flashing for 2-3 seconds. And the hit clone button briefly again. This lit up to blink all the 25%, 50%, 75% and 100% leds. They stayed lit until each percentage was cloned and then went out sequentially. The cloning took 90-120 minutes. The was virtually no heat produced. Cloned drive worked perfectly in the source computer (2240 into 2280) EXCEPT that target retained the original source 1TB partition with remainder being 5GB recovery and a 950 non alloted partitions. In my case, the recovery partition was between the primary (healthy) one and the empty one, so that I could not use Window's disk management to resize the healthy Primary into the empty one. There is NO Windows utility to move partitions but I had EaseUS Patition Manager on another computer. Using the deck with USB connection, it was easy and safe to resize the target SSD to its full capacity. I do not know if any cloning decks "automatically" adjust the target partition. A number of software cloning programs do, however. For me, a deck is easier and safer. There may be some quality control issues with these decks, so check them out quickly. Also, be sure your M.2 SSD to be cloned is PCIe and not SATA.

Having multiple functions in one device appealed to me, as an enclosure for adapting my SSD to my PCIe slot was not effective. My system only has one PCIe slot, anyway and I need it for a GPU upgrade, but warnings about my SSD failing can not be ignored. At only three dollars difference between a Samsung 512 GB SSD and 1 TB SSD, I went with the larger as a replacement. Buying a utility to format, partition and clone the new SSD was more expensive than this docking unit. So, I bought one to ease my pain over the failing drive (it just passed the warranty period a few months ago)!More pain was waiting, however. The SSK docking station I received was not fully functional. It would not reliably recognize and read an SSD in the Source bay. The Target bay worked fine, but obviously, cloning was not in the picture. I was able to format and partition my new SSD using the SSK docking station's Target bay.Unlike other reviewers, I did not feel the need to partition and format the SSD before the SSK docking station could use it. I interpreted the instructions as making the point that one needs to prepare the SSD drive for cloning, then, not for simple use! Further, NTFS is not specified in the instructions. So, there is no need to be very worried here.I contacted SSK both directly by email and through Amazon. Their responses were very quick and effective. The troubleshooting did not resolve the Source bay symptoms, though.Admirably, they sent me a replacement at no cost, not even for shipping. Further, they did not require a return of the original unit. It arrived in just a few days and I found it to work very well.The 512 GB SSD was cloned in less than 15 minutes. The cloned SSD worked perfectly fine in my desktop computer, booting and running everything as before.Now, considering the faulty initial fulfillment and the replacement, I must give SSK props for customer service and the overall product performance. Of course, quality control may need to be improved. Had a second replacement been necessary, I would not have kept the unit. I would have proceeded in a different direction. One bad unit would not repel me, though, as no brand is without a fluke. SSK could be attentive enough to monitor the frequency of disfunctional docking stations and take corrective measures. That's just good business. Customer support is as important as quality of product for me. If you take my money and forget about me, I'm going to forget about you. That's just the way it is.So, I will rate them fully five stars. I like a company that sees a problem and fixes everything quickly and professionally. Kudos for prompt response, good troubleshooting and acting responsibly with replacement product at no charge for anything. That's great performance in my book. Buy it and use it well-- there's no need to spend three or four times more money. Paying more does not always mean a better product. Use that saved money for some upgrade to your system.Be well.Be safe.

I had used cloning hardware before with the older 3.5" drives, but have since turned to software cloning until I found this tiny setup. It is much faster and easier with this and more cost effective. My main purpose is to always keep a good backup of my main operating system so I could simply swap it over in the event the drive was corrupt or failed. I initially had issues with the first unit received by the awesome support team didn't leave me hanging and help to trouble shoot with a firmware update. After that didn't resolve the issue, they quickly ensure that I had a working unit asap. Now that is a support I can feel confident in continuing to buy their products.
